单选题Many of the most damaging and life threatening types of weather, such as torrential rains and severe thunderstorms, begin quickly, strike suddenly, and disappear rapidly, de-stroying small regions while leaving neighboring areas untouched. (79) Conventional (普通) computer models of the atmosphere have limited value in predicting short-lived local storms because the available weather data are generally not detailed enough to allow com-puters to see clearly the small atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at location typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large re-gions than they do forecasting specific local events.Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or "nowcasts", was impracticable. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were beyond overcoming. Fortunately, scientific and technological advance have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observations over large regions at a rela-tively low cost. Communication satellites can transmit data around the world cheaply and immediately, and modern computers can quickly compile and analyze this large volume of weather information. (80) Meteorologists (气象学家) and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, nowcasting is becoming a reality.

单选题A group of people who share the same interests and way of life is called a society. Sociology is the science that examines human society. The term sociology is derived from the Latin word socius, which means "companion, union of people". Sociologists are interested in how a society began and how it grew. They also study the levels within a society. For example, the child is part of the family, the family is part of the neighborhood, and the neighborhood is part of the community. There are many different groups, and sociologists are interested in the effect that these groups have on people. A Frenchman named Auguste Comte made sociology a separate science in the l"830s. He suggested that a new science was necessary to study a society of people. A famous book, Principles of Sociology, was published by an Englishman, Herbert Spencer, in 1882. This book had an unprecedented(史无前例的) effect on the science of sociology. In this book, Spencer theorized that a society"s customs evolved, or grew, from very simple to more complicated and advanced. This theory shows the influence that Charles Darwin (who believed that man had evoked from very simple forms to the present human) had on Spencer.

单选题England is not a big country: from north to south and from east to west it is only about three hundred miles across. But for a small country it has a surprising range of climate. People who have never visited England, or who have visited only one part of it, often make the mistake of thinking that it is a cold and wet country. Except for the summer months of June to September, this is probably true of the north of England and the Midlands. In the south, however, the climate is much more pleasant. One result is that when people retire from a job in the north they often prefer to move down to the milder south. Perhaps the warmest part of the country is the southwest, which consists of the counties of Devon and Cornwall. The warm Gulf Stream flows across the North Atlantic Ocean from the Gulf of Mexico and makes the coastal regions of the southwest quite warm. Palm trees, bamboo (竹) and many semi-tropical (亚热带的) plants grow well in the southwest of England. Flowers and vegetables ripen (成熟) as much as a month earlier than those elsewhere. Farmers in the area obtain a higher price for their vegetables and flowers because they are read earlier. In winter there may be several feet of snow in other parts of England, but there will probably be no snow at all in the southwest. This may be one of the reasons why the southwest is one of England"s most popular holiday areas.

单选题I was only eight years old when the Second World War ended, but I can still remember something about the victory celebrations in the small town where I lived.(76) We had not suffered much from the war there, though like most children of my age, I was used to see-ing bombed houses in the streets and the enormous army lorries passing through. But both at home and at school I had become accustomed to the phrases "before the war" and "when the war's over." "Before the war," apparently, things had been better, though I was too young to understand why, except there had been no bombs then, and people had eaten things like ice cream and bananas, which I had only heard of. When the war was over, we would go back to London, but this meant very little to me. I did not remember what Lon-don was like.What I remember now about VE Day was the afternoon and the evening. It was a fine May day. I remember coming home at about five o'clock. My father and mother came in about an hour later. After dinner I said I wanted to see the bonfire (篝火), so when it got dark my father took me to the end of the street. The bonfire was very high, and some peo-ple had collected some old clothes to dress the unmistakable figure with the moustache (小胡子) they had put on top of it. Just as we arrived, they set light to it. The flames rose and soon covered the "guy." Everyone was cheering and shouting, and an old woman came out of her house with two chairs and threw them on the fire to keep the fire going.I stood beside my father until the fire started to go down, not knowing what to say. He said nothing either. He had fought in the First World War and may have been remem-bering the end of that. At last he said, "Well, that's it, son. Let's hope that this time it really will be the last one. \

单选题Passage 1A scientist who wants to predict the way in which consumers (消费者) will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending. If an economist were asked which of three groups borrow most —people with rising incomes, Stable incomes, or decreasing incomes—he would probably answer, those with decreasing incomes. Actually years 1947—1950, the answer was: people with rising incomes. People with decreasing incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions(假设) about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true. The expectations of price increases may not stimulate buying. One typical attitude was expresser by the wife of a mechanic in an interview at a time of rising prices.“In a few months,” she said,“we’ll have pay more for meat and milk; we’ll have less to spend on other things. “Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be disliked and buyer’s resistance may be produced. This is shown by the following typical comment: “I just don’t pay these prices; they are too high.” The investigations mentioned above were carried out in America; condition most helpful to spending appears to be price stability. If prices have been stable and people consider that they are reasonable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices is based on a correct understanding of consumer psychology(心理学).
